Abstract
Among carbohydrate active enzymes, glycoside phosphorylases (GPs) are valuable catalysts for white biotechnologies, due to their exquisite capacity to efficiently re-modulate oligo- and poly-saccharides, without the need for costly activated sugars as substrates. The reversibility of the phosphorolysis reaction, indeed, makes them attractive tools for glycodiversification. However, discovery of new GP functions is hindered by the difficulty in identifying them in sequence databases, and, rather, relies on extensive and tedious biochemical characterization studies. Nevertheless, recent advances in automated tools have led to major improvements in GP mining, activity predictions, and functional screening. Implementation of GPs into innovative in vitro and in cellulo bioproduction strategies has also made substantial advances. Herein, we propose to discuss the latest developments in the strategies employed to efficiently discover GPs and make the best use of their exceptional catalytic properties for glycoside bioproduction.

Abstract
Phosphorylases are useful catalysts for the practical preparation of various sugars. The number of known specificities was 13 in 2002 and is now 30. The drastic increase in available genome sequences has facilitated the discovery of novel activities. Most of these novel phosphorylase activities have been identified through the investigations of glycoside hydrolase families containing known phosphorylases. Here, the diversity of phosphorylases in each family is described in detail.

Abstract
Carbohydrate phosphorylases are readily accessible but under-explored catalysts for glycoside synthesis. Their use of accessible and relatively stable sugar phosphates as donor substrates underlies their potential. A wide range of these enzymes has been reported of late, displaying a range of preferences for sugar donors, acceptors and glycosidic linkages. This has allowed this class of enzymes to be used in the synthesis of diverse carbohydrate structures, including at the industrial scale. As more phosphorylase enzymes are discovered, access to further difficult to synthesise glycosides will be enabled. Herein we review reported phosphorylase enzymes and the glycoside products that they have been used to synthesise.

Abstract
Lin1840 is a putative β-glucosidase that is predicted to be involved in 1,2-β-glucan metabolism since the lin1839 gene encoding a 1,2-β-oligoglucan phosphorylase and the lin1840 gene are located in the same gene cluster. Here, Lin1840 was crystallized. The crystals of Lin1840 diffracted to beyond 1.8 Å resolution. The crystal belonged to space group I121, with unit-cell parameters a = 89.75, b = 95.10, c = 215.00 Å, α = 90.00, β = 96.34, γ = 90.00°.

Abstract
Galacto-N-biose/lacto-N-biose I phosphorylase (GLNBP) is the key enzyme in the enzymatic production of lacto-N-biose I. For the purpose of industrial use, we improved the thermostability of GLNBP by evolutionary engineering in which five substitutions in the amino acid sequence were selected from a random mutagenesis GLNBP library constructed using error-prone polymerase chain reaction. Among them, C236Y and D576V mutants showed considerably improved thermostability. Structural analysis of C236Y revealed that the hydroxyl group of Tyr236 forms a hydrogen bond with the carboxyl group of E319. The C236Y and D576V mutations together contributed to the thermostability. The C236Y/D576V mutant exhibited 20°C higher thermostability than the wild type.

Abstract
Intestinal colonization of bifidobacteria is important for the health of infants. Human milk oligosaccharides (HMO) have been identified as growth factors for bifidobacteria. Recently, a bifidobacterial enzymatic system to metabolize HMO was identified. 1,3-β-Galactosyl-N-acetylhexosamine phosphorylase (GLNBP, EC 2.4.1.211), which catalyzes the reversible phosphorolysis of galacto-N-biose (GNB) (Galβ1→3GalNAc)] and lacto-N-biose I (LNB) (Galβ1→3GlcNAc), is a key enzyme to explain the metabolism of HMO. Infant-type bifidobacteria possess the intracellular pathway to specifically metabolize GNB and LNB (GNB/LNB pathway). Bifidobacterium bifidum possesses extracellular enzymes to liberate LNB from HMO. However, Bifidobacterium longum subsp. infantis imports intact HMO to be hydrolyzed by intracellular enzymes. Bifidobacterial enzymes related to the metabolism of HMO are useful tools for preparing compounds related to HMO. For instance, LNB and GNB were produced from sucrose and GlcNAc/GalNAc in 1 pot using 4 bifidobacterial enzymes, including GLNBP. LNB is expected to be a selective bifidus factor for infant-type strains.

Discovery of nigerose phosphorylase from Clostridium phytofermentans. Appl Microbiol Biotechnol 2011; 93:1513-22.

Abstract
A novel phosphorylase from Clostridium phytofermentans belonging to the glycoside hydrolase family (GH) 65 (Cphy1874) was characterized. The recombinant Cphy1874 protein produced in Escherichia coli showed phosphorolytic activity on nigerose in the presence of inorganic phosphate, resulting in the release of D-glucose and β-D-glucose 1-phosphate (β-G1P) with the inversion of the anomeric configuration. Kinetic parameters of the phosphorolytic activity on nigerose were k(cat) = 67 s(-1) and K(m) = 1.7 mM. This enzyme did not phosphorolyze substrates for the typical GH65 enzymes such as trehalose, maltose, and trehalose 6-phosphate except for a weak phosphorolytic activity on kojibiose. It showed the highest reverse phosphorolytic activity in the reverse reaction using D-glucose as the acceptor and β-G1P as the donor, and the product was mostly nigerose at the early stage of the reaction. The enzyme also showed reverse phosphorolytic activity, in a decreasing order, on D-xylose, 1,5-anhydro-D-glucitol, D-galactose, and methyl-α-D-glucoside. All major products were α-1,3-glucosyl disaccharides, although the reaction with D-xylose and methyl-α-D-glucoside produced significant amounts of α-1,2-glucosides as by-products. We propose 3-α-D-glucosyl-D-glucose:phosphate β-D-glucosyltransferase as the systematic name and nigerose phosphorylase as the short name for this Cphy1874 protein.

Abstract
Glycoside phosphorylases are a special group of carbohydrate-active enzymes, with characteristics in between those of glycoside hydrolases and glycosyl transferases. The phosphorylases from family GH-112 are exceptional because they employ galactose-1-phosphate instead of glucose-1-phosphate as glycosyl donor. Different acceptor specificities have been observed in this family, ranging from l-rhamnose to GlcNAc, GalNAc and a combination of the latter. Three new phosphorylases from previously unexplored branches of the phylogenetic tree of family GH-112 have now been characterized to shed more light on this divergence in acceptor specificity. The enzymes from Erysipelothrix rhusiopathiae and Streptobacillus moniliformis were found to prefer GalNAc as acceptor, while that from Anaerococcus prevotii displays similar activities on GalNAc and GlcNAc. These results confirm the correlation between the amino acid residue at position 162 and the enzyme's specificity, i.e. a threonine in the former group and a valine in the latter. However, mutagenesis of residue 162 did not allow the rational transformation of the substrate preference, as the substitution of valine by threonine in the enzyme from Bifidobacterium longum did not tighten its specificity towards GalNAc. Unexpectedly, introducing an isoleucine at position 162 increased the preference for GlcNAc as acceptor, which illustrates that the structure-function relationships in β-galactoside phosphorylases are not yet completely understood. Several other positions have also been examined by mutational analysis but true determinants of the acceptor specificity in family GH-112 could not be identified.

Abstract
D-Galactosyl-beta1-->4-L-rhamnose (GalRha) was produced enzymatically from 1.1 M sucrose and 1.0 M L-rhamnose by the concomitant actions of four enzymes (sucrose phosphorylase, UDP-glucose-hexose 1-phosphate uridylyltransferase, UDP-glucose 4-epimerase, and D-galactosyl-beta1-->4-L-rhamnose phosphorylase) in the presence of 1.0 mM UDP-glucose and 30 mM inorganic phosphate. The accumulation of GalRha in 1 liter of the reaction mixture reached 230 g (the reaction yield was 71% from L-rhamnose). Sucrose and fructose in the reaction mixture were removed by yeast treatment, but isolation of GalRha by crystallization after yeast treatment was unsuccessful. Finally, 49 g of GalRha was isolated from part of the reaction mixture with yeast treatment by gel-filtration chromatography.

Abstract
We characterized three d-galactosyl-beta1-->3-N-acetyl-d-hexosamine phosphorylase (EC 2.4.1.211) homologs from Clostridium phytofermentans (Cphy0577, Cphy1920, and Cphy3030 proteins). Cphy0577 and Cphy3030 proteins exhibited similar activity on galacto-N-biose (GNB; d-Gal-beta1-->3-d-GalNAc) and lacto-N-biose I (LNB; d-Gal-beta1-->3-d-GlcNAc), thus indicating that they are d-galactosyl-beta1-->3-N-acetyl-d-hexosamine phosphorylases, subclassified as GNB/LNB phosphorylase. In contrast, Cphy1920 protein phosphorolyzed neither GNB nor LNB. It showed the highest activity with l-rhamnose as the acceptor in the reverse reaction using alpha-d-galactose 1-phosphate as the donor. The reaction product was d-galactosyl-beta1-->4-l-rhamnose. The enzyme also showed activity on l-mannose, l-lyxose, d-glucose, 2-deoxy-d-glucose, and d-galactose in this order. When d-glucose derivatives were used as acceptors, reaction products were beta-1,3-galactosides. Kinetic parameters of phosphorolytic activity on d-galactosyl-beta1-->4-l-rhamnose were k(cat) = 45 s(-1) and K(m) = 7.9 mm, thus indicating that these values are common among other phosphorylases. We propose d-galactosyl-beta1-->4-l-rhamnose phosphorylase as the name for Cphy1920 protein.
